1. A deaerator heater supplies 150 L/min of deaerated feedwater into a booster pump at 115 oC pumping temperature. The heater pressure is maintained at 100 kPag by bleed steam. Pump centerline is located 1 m above the floor level. Suction line losses is 0.60 m. Determine the minimum height of water level in the heater that must be maintained above the centerline of the pump to avoid cavitation, if the pump to be installed has a required suction head of 5.8 m.

A pump draws saturated water from a condenser which is maintained at 32.15°C. The friction head losses between pump and condenser is measured to be 1.5 m. Determine the minimum height of water level (above pump centerline) in the condenser if NPSH required required for the pump is 3.5m Draw the FIGURE
Water with a specific heat of 1 BTU/lbmoF is pumped using a 1-hp jet pump from a well that is 20 ft deep into a vented water vessel 160 ft above the ground. In the process, 400 BTU/min of heat is lost from the system. What is the temperature (oF) of the water as it enters the vessel if the flow rate of the water is 5 gal/min? Assume the temperature of water in the well is (35oF).

Please with proper solution. Thanks An R-22 compressor has a 5 percent clearance volume and a displacement rate of 80 L/s and pumps against a condensing temperature of 40°C. For the two different evaporating temperatures of +10 °C, compute the refrigerant flow rate in kg/s assuming that the clearance volumetric efficiency applies.
a supply tank having 14m long and 1.7m diameter is used to store fuel oil with 34degree API at 110degree C. if the tank is used for diesel power plant consuming 62 kg/hr of fuel, determine the number of days the supply tank can hold continuous operation.
What are the frictional losses to be considered when calculating power consumption of a pump under operation?
Pump Horsepower in Brine System. A pump pumps 0.200 ft3/s of brine solution having a density of 1.15 g/cm3 from an open feed tank having a large cross-sectional area. The suction line has an inside diameter of 3.548 in. and the discharge line from the pump a diameter of 2.067 in. The discharge flow goes to an open overhead tank, and the open end of this line is 75 ft above the liquid level in the feed tank. If the friction losses in the piping system are 18.0 ft lbf/lb m, what pressure must the pump develop and what is the horsepower of the pump if the efficiency is 70%? The flow is turbulent.
